It appears AT&T is making itself a laughing stock again. For it's first Android phone allowed to make wifi calls, it didn't choose a current-year model. It picked the G4. Sheesh, at least pick the G5. http://androidandme.com/2016/06/new...ble-on-the-lg-g4-coming-soon-to-more-devices/
Skype, Hangouts, and Vonage all have their benefits, but the niche filled by wifi calling is different from those.
Are there situations where you need wifi calling? The only place I really need wifi calling is overseas calling.
For a free service, wifi calling is the best. From the mobile phone, ANY number can be called (cell or landline), with no matching app required on the receiving device ( obvious if your calling a landline or business) ATT wireless quality fluctuates at my home. So using my Wi-Fi router ensures a crisp, clean and high quality call consistently. Also useful from inside stores that offer free Wi-Fi, but where the store building structure reduces the ATT wireless signal quality. So in addition to calling from overseas, calls originated domestically in poor signal areas benefit from Wi-Fi calling. I use it daily. Sent from my iPhone using Tapatalk
